PURPOSE:To readily and surely store and set automatic play sounds and express music sheet with automatic play sounds by subsequently operating input switches arrayed with respect to the pitch and note length corresponding to music sheet. CONSTITUTION:In the case of setting the music to play automatically, an address generator 17 is initially set, after which the operators 41a, 41b ... of the panel face are operated; for example, in the case of quarter note at a pitch of C, the operator 41c is operated and a switch 11c is turned on, then outputs are generated in ORs 12a, 14c and the digital pitch information of C and the digital note length of the quarter note are generated from encoder delays 13, 15. The generator 17 is then advanced to the state of the No. 2 address assignment by the output of a differentiation circuit 21 and the pitch and note length information corresponding to the switch 11c is written and stored in the No. 2 address of a memory device 16 in correspondence to the output of the differentiation circuit 23. |
